and it goes over three different methods of DLL injection. How would I preven

Since this poster alludes that he is investing game anti-hacking, let me shed some light on what I think. As a ex cheater.

Just a pointer about game anti-hacking.

The best way is to let the server run the core game logic. e.g. In a first person shooter, monitor movements the clients send to the server. Don't allow them to move around at random. Let the server tell the clients where each player is based on its own logic. Don't ever just forward commands. They could be bogus.

Who cares if the hacker hacks his own client? just refuse it on the other ones and all is good. For starcraft maphacks, solution is simple. Don't give out gamestate for areas that should be unknown. It saves bandwidth too.

I was a big cheater in Delta Force (its an old game). The main trick I used was to warp anywhere in the game by modifying the process memory directly. No DLL required!

The best way would be to ensure no untrusted process gets Administrator access, or runs as the same user account as your application. Without this access, code injection into your application is not possible; and once such a process gets that access, it can cause all kinds of mischief without needing to inject itself into another process - the injection just makes it easier to hide.
